Many thanks to Kevin, as his suggestion solved my problem. I originally did not think it was related to the BIOS, since other operating systems were not experiencing the same problem. But I used the PS2 configuration utility to change the power mode to "Custom", and then disabled the hard drive turn-off for AC power, and the problem is now solved. Since I only have a CDROM drive for the 600X (no floppy), it took quite a bit of work to get the PS2 utility loaded. I have included the detailed steps below in case anyone needs them. Again, thanks Kevin. And sorry about the "HTML crap" :) Steps: *Obtaining & Preparing the PS2 utility* 1. Downloaded the executable for the configuration utility from IBM: http://www-1.ibm.com/support/manager.wss?rs=0&rt=0&org=psg&doc=RMIE-3AXE 3E 2. Ran the executable from a DOS prompt on another machine that had a floppy drive. (The executable extracts the files to the floppy.) 3. Burned the files from the floppy to a CDR. *Preparing the Thinkpad Hard Drive* 1. Reinstalled FreeBSD 4.5 Stable with the boot manager, leaving some space on the hard drive for a DOS partition. 2. Booted to a command prompt from a Win98SE CDROM (as I do not have a floppy or other removable boot device) 3. FDISKed, created a primary DOS partition, marked as active, restarted. (It turns out that I needed to create the DOS partition from the Windows version of FDISK in order for the partition to be recognized by the FORMAT command. FreeBSD's DOS partition was not recognized.) 4. Again, booted to command prompt from Win98SE CDROM 5. Formatted the DOS partition as bootable (format c:/s) *Installing and Running the PS2 utility* 1. Copied the files from the CDR created previously to a directory on the DOS partition. 2. Ran the UINSTALL command from that directory to install the PS2 utility. (This will create a directory called THINKPAD on the DOS partition). 3. Rebooted and ran the following PS2 commands: ps2 pmode custom ac <enter> ps2 disk 00 ac <enter> -----Original Message----- From: Kevin Oberman [mailto:oberman@es.net] Sent: Thursday, April 04, 2002 12:28 PM To: Kenan Cc: mobile@freebsd.org Subject: Re: Thinkpad 600 Power Management Issues (HD turned on and off) > From: "Kenan" <info@djkenan.com> > Date: Thu, 4 Apr 2002 00:42:41 -0600 > Sender: owner-freebsd-mobile@FreeBSD.ORG > > I have recently installed 4.5-stable on a Thinkpad 600X (BIOS version > ITET53WW), and the hard drive sounds like it is being turned on and off > every few seconds.

Most ThinkPads, including the 600X, use a DOS utility, PS2, to configure BIOS. Only a very few things can be configured from the startup BIOS screen. PS2 is available as a bootable floppy image from the IBM web site. Look for "DOS Configuration Utility" in downloads. "ps2 ?" will get you started. There are LOTS of APM options including disk spin-down. I have my system configured to spin down the disk after a minute when on battery power and that works OK. I have it leave the disk spun up when plugged into AC power. R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
